The World Health Organization has also issued a chronology of key events in both human and poultry outbreaks of the H5N1 virus.

The chronology comes one month after the confirmation of the first three human infections of the virus. The clinical data released Thursday indicates health care staff may ignore milder cases of the illness. Therefore, the WHO warns that the current small number of laboratory-confirmed cases is not an accurate indication of the potential threat to human health.
